PROFESSOR GLENN HIBBARD NANOARCHITECTURE FOR STRONGER MATERIALS THE POWER OF PARTNERSHIP A bridge is mostly empty space; it is the unique shape of the trusses and struts that provide its strength. Professor Glenn Hibbard and his team are applying that same principle on the nano scale, designing intricate 3D One nanometre is to the thickness of a human hair as Department of & Engineering and structures that lead to lighter, stronger materials for use in the aerospace one inch is to a mile. It is hard to imagine designing Professor Charles Mims of the Department of Chemical industry and more. something so small, but U of T Engineering researchers Engineering & Applied Chemistry. can. Common devices — including the integrated circuit Hibbard’s team builds their scaffolds using polymers (plastics) which are easy boards found in smartphones, cars, TVs and even kitchen One unique technology in development at OCCAM is a to manipulate but do not have much compressive strength. They then coat appliances — contain layers of electrically conducting transfer system that allows the movement of samples these scaffolds with tiny crystals of high-strength metals.
